To aZZ whom it may concern:

3e it known that we, EDWARD A. BYRNE and EDWARD KosIoL, both citizens of the United States, residing at Cincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Lubricators for Loose Pulleys, &c., of which the following is a specification, reference be ing had therein to the accompanying drawlugs.

Our invention comprises a lubricator which insures aregular supply of oil to hubs of loose pulleys, drums, and other similar revolving appliances.

The device consists, essentially, of a suitable fount or reservoir having a cylindrical opening or bore of such diameter as to fit snugly around the hub of the pulley or drum, the reservoir being usually made in the shape of a hollow annulus and coupled to said hub by a short tube that communicates with an oil-channel in the former. Furthermore, this connecting-tube communicates, either directly or indirectly,with a scoop-pipe whose receiving end or mouth is so arranged as to cause the lubricant to be ejected into said tube at every revolution of the reservoir, as hereinafter more fully described.

Another feature of our invention comprises a novel combination of devices for regulating the discharge of oil through the scoop-pipe and connecting tube, as hereinafter more fully described.

Our invention further consists in providing the reservoir with a pendulous barrier that.

effectually retains the oil at the bottom of said reservoir, no matter how rapidly the pulley may revolve, suitable provision being made for the passage of the scooppipe, as hereinafter more fully described.

In the annexed drawings, Figure 1 is a vertical section of one form ot'our lubricator,taken in the plane of the scoop-pipe. Fig. 2 is an enlarged axial section of the feed devices of the same. Fig. 3is a horizontal section thereof, taken in the plane of the ports 0. Fig. 4 is a sectional elevation of a modification of our invention. Figs. 5 and 6 are sections of other modifications.

A represents the fount, reservoir, or other vessel that contains the lubricant, which res- (No model.)

ervoir is usually made in the shape of a hollow or tubular annulus, and has a cylindrical bore or opening, B, adapted to iit snugly around the hub G of a loose pulley, drum, or other revolving appliance.

D is the shaft, spindle, or other bearingupon which the pulley is journaled.

E is the filling-neck of the fount, said neck being provided with a screw-threaded or other cap, F, the removal of which permits said fount to be charged with oil.

The interior of the fount has a raised seat, G, upon which rests the lower end of a cylinder, H, the upper end of the latter being closed by an annular flange or collar, I, of a tube, J, which tube is of less diameter than said cylinder, and is threaded externally at K to engage in the outer end of an oilchannel, L, of the loose hub C. The lower portion of tube Jhas a passage, M, (seen in Fig. 2,) while its upper portion is threaded internally to admit a screw plug or regulator, N, having a nick, n, in its outer end. i is a similar nick or groove in the flange or collar I.

O O are transverse ports of the feed-tube J.

P is a scoop-pipe whose inner end is at tached to cylinder H and near the base of the same, while the receiving end or mouth of said pipe is in close proximity to the outer wall of the fount.

To apply thislubricator,the cylindrical bore B of the same is first slipped over the hub G, and the cap F is detached, as seen in Fig. 5, to permit the feedrregulating devices being fitted in their proper place, as follows: The cylinder H is passed down through the open neck E, and the scoop pipe P of said cylinder is turned so as to present its mouth in the direc tion the pulley is to revolve. The tube J is then inserted in the cylinder, and its end K is engaged with the threaded portion of the hub channel L, afterwhich act said tube is screwed home by inserting an implement in the nick i of the same. It is evident that the cylinder H is now clamped firmly upon the raised seat G, while the threaded portion K of tube J serves as a coupling that fastens the fonnt to the hub. After the fount is thus attached to the hub the former is filled with oil or other fluid lubricant, and the adjusting-plug N is then set so as to regulate the discharge. The

cap F being now fastened to tl1eneck,the pulley is set in motion in the direction indicated by the arrow in Fig. 1, and as the t'ount is attached to the hub it is evident these two members AG must revolve together. As the oil is quite fluid or limpid, the bulk of the same naturally collects in the bottom of the fount, only a limited portion being carried around the sides or wall of the same by centrifugal action; consequently, when the fonnt has turned around until the cylinder H is submerged in the oil, as indicated by the dotted lines in Fig. 1, the latter is at once driven through the scoop-pipe P into the annular space V between said cylinder and the tube J. As soon as the cylinder begins to assume a vertical position, the oil flows through the ports O,and then descends the communicating channels M L, thus lubricating the shaft or bearing D at every revolution of the pulleyhub G.

In the elaboration of our invention seen in Fig. at the outer wall of the reservoir proper is ridge shaped, as a A, and its margins are clamped between the flanges It R of a pair of heads, S S, the head Shaving aprolongation, T. that is bored out at B to tit around thehub of the pulley or drum. Furthermore, one end of this tubular prolongation 'lis screw-threaded to engage either with a hollow boss, U, of the head S or with a nut capable of being screwed onto said tube. Thisconstruction enables the reservoir to be made of glass, while the ends or heads of the same can be composed of metal.

A studing-box f, is shown attached to the cap F of the filling-neck, the regulator N being passed through this box, and having a square end, a, to receive a key or wrench, in order that the feed may be controlled without detaching said cap, which is a great advantage when the shafting is near a ceiling and there is not sufficient clearance to admit a screwdriver being inserted in said filling-neck.

Either of the oilers seen in Figs. 1 or 4 will suffice when the pulley is driven at a moderate speed; but when a very high velocity is necessary we preferusing the construction seen in Figs. 5 and 6. In these illustrations annular grooves a a are made in the heads or ends of the reservoir, which grooves receive knifeedged bearings 20 w of arms \V XV, that project rigidly from a heavy pendulous barrier, X, interposed athwart the lower portion of the vessel A, said barrier being slotted vertically, as at w, to permit a free passage of the scoop-pipe l, which in this case has a screw, 1), and nipple p, but no feed-regulating appliance. The screw engages with the raised seat G, while the nipple enters a counterbore, Z, in the outer end of the oil-channel L. Owing to the weight of barrier X and the free manner in which it is suspended, it always hangs vertically below the axis of shaft D, and thus serves as an obstruction that arrests the oil and prevents it being carried around within the reservoir, no matter how rapidly the pulley may revolve. At every revolution of the reservoir the scoop-pipe I passes freely through the slot as without moving said barrier. Finally, in Fig. 6, a groove,Y, is made in the center of the reservoir, and the barrier is shaped to enter said groove, by which arrangement the pipe I will be enabled to scoop up the oil as long as there is any left in the fount.

Ye claim as our invention 1. An oilerconsisting of a fount or reservoir completely surrounding the hub of a loose pulley or drum, and coupled to the same for the purpose of revolving therewith, said fonnt being provided with a scoop thatis submerged at every revolution of the hub, and thereby ejects the lubricant into a channel of the latter, substantially as herein described.

2. An oiler consisting of a fount or reservoir completely surrounding the hub of a loose pulley or drum, and coupled to the same for the purpose of revolving therewith, said fount being provided with a scoop thatissnbmerged at every revolution of the hub, and thereby ejects the lubricant into a feed-regulator communicating with a channel of said hub, substantially as described.

3. The combination, in an oiler, of an annularfount, A B, fillingneek E, cylinder H, tubular screw-coupling K M, and scoop-pipe P, said coupling K being adapted to engage with the channel of a loose pulley-hub, for the purpose specified.

5. The combination, in an oiler, of the an nular fount A. clamped between the flanged heads R S R S, the head R S having a tubular prolongation, B T, engaging with the opposite head R S, and the tubular screwcoupling K of the feed device H P being engaged with this cylindrical prolongation, for the purpose described.
